Hi don4blues,
If the power steering has a buzzing noise with no leakage in fluids, the pump or pressure hose should be the cause.
With the car nearly a decade old and 55k miles, I would recommend replacing the timing belt. Tuneup is not that important if during regular services those had been checked, unless you have any problem affecting the performance etc. However no harm in getting it checked if you are there.
